Above you said +1 to "educate browser developers" to be less draconian. 
Here you say that the "XML community really want to keep it that way". 

John Cowan claimed there to be (I think) 22 fatal error categories in 
XML. And an not easy to count amount of -in theory- not fatal errors - 
which still, according to John, are treated as fatal errors in all 
known XML parsers. It is not clear to me how most in the XML community 
want to keep it - whether they want to keep all not fatal errors as 
fatal, or if they are open to discern between the kinds of errors.

One should think that A) browser vendors could have a look at the 
countless non-fatal errors an make sure that they are not treated as 
fatal. And B) that they could be Opera friendly instead of Firefox 
draconian w.r.t. fatal errors.
